General description of the machine The principal parts of the machine are the machine frame (Figs. 2, 3 and 4) a paper carriage 2 displaceably attached to carriage running rails 3 and 4 fixed to the machine frame, and totalizers 5 and 6, an idle totalizer l and a complement totalizer 8 (Figs. 1 and 3), provided for a definite booking operation and attached to a suspension rail 9 fixed to the paper carriage 2. The machine is further provided with a casing I0 carrying the calculating elements and being fixed to the front side of the machine frame I. In the machine frame 1 a typewriter keyboard I l is arranged with shift keys I2 and a carriage return key 13 (Figs. 1 and 2) for controlling the carriage return mechanism. Also keys M of a decimal tabulator have been provided in the machine frame I A carrying frame 15 (Figs. 1, 3 and 5) constitutes a further To this end the totalizers to 8 corresponding to the column I to IV of form 206 (Fig. 18) are suspended from the suspension rail 9 for the.to-.

talizers (Figs. 1 to 3) and the tabulator' stops 3! (Figs. '3 and 4) associated therewith are adjusted or set on the bar or shaft H5. The form ZEJili's' also properly adjusted around the platen and set to writing position with respect to the first writing line. By actuating carriage release lever l the paper carriage 2 is then moved into the extreme right-hand position.

In order to effect the booking entries in columns I to III on the first writing line of form 299, it is necessary to bring the paper carriage 2 with the totalizers 5 to l or the columns I to III of form 299, respectively, into the respective required working or operating position. This is effected by depressing the tabulator key corresponding to the value to be booked, of the decimal tabulator keys 14, whereby the paper carriage 2 is released for a movement to the left, which is stopped at the required position by the cooperation of the corresponding tabulator stop 37 and the tabulator slide 22 (Figs. 3 and 4) associated with the depressed tabulator key.

When running into the selected operating positions, the totalizers act, as the case may be, by

means of control plates 262, 263 and 294 (Fig. 4)

on controlling members 26L 264, 278 (Figs. 7

and 2) thereby effecting, in a manner to be'hereinafter described under the heading Total taking process in the calculating mechanism, the release of the calculating mechanism, the adjustment of the particular species of calculation and the actuation of a coupling sleeve 285 (Fig.

v2) for selective coupling of the calculating mechanism driving wheels 296 and 297 with the driving shaft 296 (Figs. 2 and 6), on which shaft 298 said driving wheels 2116 and 237 are rotatable, but not shiftable axially. In the same manner the totalizers, when moving into operating position, will slide the forwardly extending flanges 299 of the guide plates 2m fixed to them, below a roller 2!! (Figs. 2, 4 and 16) rotatably fixed to an angle shaped guiding member 212 screwed to the front side 2l4 of the casing It by means of screws 2| 5. When moving into their operating position, the guiding plates am act also on member hereinafter described under the heading Total-taking process in the calculating mechanism without actuating, however, any further mechanism. Further, when moving into their operating position, the totalizers are caused to selectively engage, according to the respective operating position, with the driving or master wheels 2H5 and 21'! (Figs. 2 and 6) fixedly arranged on the shaft 263 and with the driving wheels 266 and 26? adapted to be couplediselectively to the shaft 268.

For the purpose of calculating and writing down the values to be booked, the respective calculating keys i5 are depressed successively and with every'depressed key the following operations will be started. If, for instance, the calculating key corresponding to the numeral 1 of the value 153.42 to be booked first, is depressed, the associated key lever 2l8 is swung around its shaft 12, whereby in turn the cam I43 associated with the swingable key lever 218 is coupled for one rotation to the shaft 81 driven continuously by the motor l8. During the first half rotation of the cam I43 now taking place, the differential member I41 (Figs. 4 and 6) which is always held against the cam I43 by means of springs I48 and 219, will follow the descending cam slope under action of the said springs. In consequence, the differential member I 41 is caused to make a downward movement, atthe beginning of which the inclined face 220 (Figs. 4 and 6) of the slide acts on the ledge 22! of the swinging frame 22l, 222, 223, fast on the shaft 224 and causes the frame and shaft to swing in the direction of arrow 225 against action of spring 226 bearing upon lever 22'! fast on shaft 224. The spring 226 continually pulls the bent-offportion 228- (Fig. 2) of lever 22! against the backwall of the casing l0 thus determining the normal position of shaft 224 and of the parts or elements mounted thereon. When the swinging frame 22L 222, 223, 224 swings as above indicated, the levers 229, 230, 23l and 232 (Figs. 2, 6) associated with the driving or master wheels 206, 201, 2l6 and 2|! and fixed on shaft 224 are also caused to swing and in turn act 'on the release levers 233 of the totalizers (Fig. 16), which are in operating position at-such times with respect to the levers 229, 239, 23! and 232. These respective release levers, according to the exemplified first booking operation, are the release levers 233 of the hundreds places of the totalizers 5 and 6 and of the complementtotalizer 8. Since the values are only written down in column III, but not calculated or entered in the totalizer 1, this has been designed as an idle totalizer and'has, therefore, no driving parts or gear, sothat in this operation the lever 230 of the swinging frame 22!, 222, 223, 224-, swings in idle motion Without acting on any totalizer release lever. The lever 234 (Fig. 6) also fast on the'shaft 22401: the swinging frame 22l, 222, 223, 224 acts during the swinging movement referred to, by its laterally bent cam portion 235 on the slide 236 in driving connection with the driving segment or sector 231, displacing it in the direction of the arrow 238 (Fig. 6). In consequence, the driving segment 23?, which in its normal position is held out of engagement with the driving wheel 239 fast on shaft 249, by the cam portion 235, is swung around its pivot screw 24! so that it is caused to engage the driving wheel 239. The lever 242 also fast on'shaft 224 is swung in the samedirection as the levers 229 to 232, whereby the lever 242 disengages the ratchet wheel 243, thus releasing the gear system" of the calculating mechanism. During its further downward movement the differential member l4! co-acts, by means of its differential cam slot 244 (Figs; 4 andfi) with the shaft 245 of theswinging'frame 245, 246, 241, 246, to the beam 246 of which the driving segment 231 is mounted to swing laterally around the screw 24L The swinging frame 245, 246, 241, 248 is thus swung in the-direction of arrow 249 (Fig; 6) around the'pivot screws 259 and the driving segment 23! which is in a fixed relation tothe swing frame 245, 246, 241, 248 in this direction of movement, partakes of this swinging movement. Due to the driving connection 237, 239 previously made, this movement is transmitted to the shaft 240 and by way of th'e'driving ele- ,ments 25I, 252, 253 and 254 to the master wheel driving shaft 208. By means of the driving wheels 2I6 and 2I1 fast on shaft 208 this movement is also transmitted to the main wheels 255 (Figs. 3, 4 and 16) of the totalizer 5 and of the complement totalizer 8, which in turn transmit this movement by way of the totalizer intermediate gears 256 and 251 (Fig. 16) to the numeral wheels 258. Now,-the numeral 1 is shown in the hundreds places of the totalizers 5 and 8 on their numeral wheels 258. No transmission by the driving wheels 206 and 201 to the totalizers 6 and 1 has been effected in this case, because in the first booking operation the coupling of these driving wheels has been controlled in such a manner, that the driving wheel205 is out of, and the driving wheel 201 isin driving connection with the shaft 208. Accordingly, the driving wheel 206 and the driving elements of'the totalizer 6 are not acted upon. The driving wheel 201, though taking part in this movement, does not transmit its movement to the idle totalizer 1, since this has no driving elements, the idle totalizer 1 being fitted only with the controlling members for controlling the calculating mechanism release and the members for setting the species of calculation. Shortly before the differential member I41 has finished its downward movement, it co-acts, by means of the angle piece I50 fast on it (Figs. 4 and 6), with its associated numeral writing key lever I 49 for the numeral 1 and causes it to swing in a clockwise direction around the pivot bar 259. By means of the intermediate member I5I the driving connection is consequently established between the lever system I5I, I55 of the type lever I54 and the fluted shaft I53 continually driven by means of the motor I8 and the type lever for typing the 1 of the value 153.42 in column I of the form 200 (Fig. 18) is operated. When the type lever printing the type falls back, the carriage escapement control mechanism (not shown in the drawings) is acted upon and the paper carriage is released for a movement to the left by one step. For the purpose of effecting the stepwise transport of the carriage 2 in the comma place, the comma place is bridged over by actuating the space key I30 or by a comma skipping device.

During the second half rotation of the cam I43 its nose acts on the differential member I41 and displaces it against action of springs I48 and 2I9 upwards into its normal position. Hereby all mechanisms actuated are caused to return to their normal positions under action of their associated springs.

With each depression of a calculating key of the calculating keys I6 for the purpose of booking operations to be performed in columns I to II, the above described operations will be repeated. The differential member 260 (Fig. 6) corresponding to number 0 has not been provided with an in.- clined face 220 for controlling the release of the calculating mechanism nor with a differential slot 244, because no differential operation has to be effected by this member. It is merely provided with an angle piece I50 to actuate the key lever for typing the O. The booking entries to be made in column III of the form 200 are recorded on the form, but are not indicated in the idle totalizer I. In order to indicate if in column III a negative balance is booked, as is the case for instance with the value 302.85, this previous negative balance is written down in inclined numerals.

I In the various booking operations the state control mechanism is always controlled in such a manner that each of the booking entries in the columns I to III is transmitted to the complement totalizer additively or subtractively according to whether a credit or debit item or sum, or a debit or credit balance, respectively, is booked. The new balances thus entered or calculated in the complement totalizer 8 are now written out or withdrawn from the complement totalizer 8 by automatic total-taking and are written down in column IV of form 200 for which purpose the following mechanisms are provided and put into operation.

Automatic total-taking The values shown in the complement totalizer 8, which have been calculated from the values booked in the columns I to III, are now to be written out or withdrawn from the totalizer 8 by means of automatic total-taking and recorded in column IV. To this end it may be assumed that first the value 417.95 is to be withdrawn from the complement totalizer 8 and written down on the first booking line in column IV of the form 200. Since the value 417.95 represents a new debit balance, that is a value introduced by addition into the complement totalizer 8, it must be withdrawn from the said totalizer by subtraction. To place the paper carriage 2 into the required position, the hundreds tabulator key I4 of the decimal tabulator corresponding to the value 417.95 is depressed, whereby the tabulator key lever 20 (Fig. 4) associated with this lever is swung in a clockwise direction around its pivot screw 2! and the tabulator rod 22 associated with lever 25 is raised. In doing so, the tabulator rod 22 renders the carriage stop lock ineffective. Consequently, the paper carriage 2 is displaced to the left-hand side by the carriage spring, this movement being limited by the tabulator stop 31 associated with the complement totalizer 8 striking against the said tabulator slide 22. In this position the hundreds wheel of the complement totalizer 8 (Figs. 3 and 16) is in engagement with the driving wheel 2I6 of the calculating mechanism, while column IV of the form 200 is in writing position.

The complement totalizer 8, when running into the above mentioned position, acts by its control plate 2532 (Figs. 3 and. 16) on the lever 26I (Figs. 2 and '7), thus causing it to swing in a clockwise direction against the action of its spring 252 around its pivot 252. Consequently, the lever 283 fast on shaft 224 is released or set free for the 7 release of the calculating mechanism gear. Further, the complement totalizer 8, when entering into the said position, acts by the control plate 203 on the state control angle lever 264 and causes it to swing in a clockwise direction against the action of its spring 284a. around the pivot screw 255 screwed into the front wall 2I4 of the casing I The elements 258 to 213 and 25I (Fig. 7) which are in driving connection with the angle lever 2'34, also participate in the movement and hereby the wheel 25I is caused to disengage wheel 252 and to engage wheel 214 (Fig. 6) whereby the direction of rotation of shaft 208 is changed and the type of calculation is changed from addition to subtraction. The complement totalizer 8 in place of the control plate 25-4 is provided with a control plate 215 swingable round a shaft 215 (Fig. 16) and when held in the position shown in said figure, the control plate 215 cannot act on angle lever 218, so that the latter is not influenced by the complement totalizer when this is moving into the position above indicated. consequence, the coupling sleeve 235 (Fig. 2) is not operated. position, the complement 'totalizer 8 'furtheracts When moving into the indicated Preparing thetotaZ-talcing operation by depressing the total-taking key 'On the shaft 12 fixed'in the carrying frame I atotal-taking key lever l9 (Fig. 3) is swingably mounted which lever in its position of rest together with the catch 289 of arm 289a is continually pressed against the locking bar 15 by means .of a spring 283 attached to said arm 283a and to a spring suspension rail 28L Said suspension rail ZBI is fixed to the inside of carrying frame l5 by means of screw 282. The catch limb 14 of locking lever T3 swingably attached to the total-taking key lever '19 by means of a headed screw 11 is continually pressed under action of spring 16, against locking bar I5 fixedly mounted in the carrying frame It. A lever 285 which is swingably mounted on the shaft 12 (Fig. 3) is caused by means ofspring 289, to act continually against a face .287 of locking bar 15 whereby the position of rest of lever 285 is determined. Lever 285 cooperates with a roller 289 fixed to a cam 85 fast to another cam 289. A coupling pawl 3| (Fig. 13) shiftably connected to the cams 289 and .85 by means of pins 290 and slots 29! is continually held against the arm 79 of the totaltaking key lever 'i'il by action of spring 82 against that .pin 29!] entered in the slot in the pawl 8| which also accommodates the sprin whereby the coupling pawl BI is held in disengaged position with respect to the coupling wheel 83 non-rotatably arranged on shaft 8?.

By the tension exerted on the cams 85 and 289 by spring 82 the roller 288 :ofthe cam 85 is pressed against a corresponding face 292 (Fig, 3) of lever 285 whereby the said .cams are retained in the position of rest shown in Fig. 3. If the total-taking key [1. is depressed,

the total taking key lever 19 is caused to swing around its pivot shaft '12 in a clockwise direction against the action of spring 283. The locking lever 23 is also displaced thereby and with its catch limb l4 slides from under the locking shaft 15 and swing around its pivot screw H in a clockwise direction under the action of spring 76 when the total-taking key lever 19 has finished its 7 cams 35 and 289 are coupled to shaft 87 continupling wheel 83 so as to engage same. Hereby the ally driven by motor l8.

Total-taking process in the calculating mechanism At the inside of the casing It a slide 293 (Figs. 3 and '7) has been arranged which is guided with its lower bent-off end 2-94 in a slot of aguide plate 295 (Fig. 9). The plate 295 is screwed by means. of screws 296 to the usual lower guide plate'29'l by which the differential members I41 are guided. When the total-taking key ll is depressed, arm 19 of the total-taking key lever 10 acts on the lower bent-off end 294 ofthe slide 293. An upper end 298 (Figs. I and 7). of slide 293 bent forward and projecting below the front side 2M of the casing I9 is jointed to an arm 299 of an angle lever 390, by means of a screw 33L The angle lever 309 is swingably mounted on a screw 32 screwed into the front wall. 2I4 of the casing I9, and a fork shaped arm 393 of the angle lever engages a pin 394 (see also Fig. l) of a slide 3E5. This slide 3.5 is arranged to be axially displaceable on the front wall 214 of the casing I!) by means of a slot 306. and a headed screw 36! screwed into said front wall 214, the slide 395 embracing and supported by the upper edge of the latter by means of a bentoff U-shaped portion 308 engaging a recess 399 (Fig. 1) of the front wall 2l4'. A spring 310 (Fig. 7) attached to slide 293 pulls the lower end 294 of same continually downwards against the arm 19 of the total-taking key lever 19, whereby the slide 335 (Fig. 1) is normally held towards the left hand side.v Both movements of the slide 395 are limited bythe screw 391, against which the right-hand end of the slot 309 lies or abutsin the position of rest. The slide 305 engages with its nose 3 the underface of a zero-setting or zero-position stop 312 (Figs. 7 and 16) screwed to a U-shaped lever 3H4 by means of screws 3l5. By means of arm 3H3 and 317 the lever 314 is swingably arranged on shaft 238, secured against lateral displacement on shaft 298 by the driving wheel 2J6 and the adjusting ring 3H3 (Fig. 2) fast on the shaft 238. The arm 3H of lever 3 is acted upon by a spring 3i9' in a clockwise direction round shaft 298, the lever acting with the zero stop 3I2 on the nose 3!! of slide 395 and pressing this slide with its bent-off portion 303 against the recess 399 of the front side 2l4 of the casing l9, thereby determining the position of rest or normal position of elements 3M, 312 and 395. A lever 320 (Fig. 7) guided by its front end 32! in a slot 322 (Fig. 1) of the front Wall 2H4 of the casing l9 and linked atits rear end 323 by means of a screw 324 to a lever 325 fast on the shaft 224 is adapted to act on slide 395 when shaft 224 is swung.

In the casing It) a release or unlocking slide 339 (Figs. 8, 9 and 10) is arranged, the. lower end of which is guided in the usual guide plate 291' for the guiding of the differential members, whereas its upper end is guided in the usual guide plate 343 (Figs. 9 and 10) forguiding the differential members, which plate 34% is screwed to the front wall 2|4 of the casing ill by means of screws 3 H. Springs 342 and 343 (Figs. 9 and 10) provided at the right and left hand sides of the unlocking or release lever 3 39 and acting on the same engage stationary spring hooks 342a and 343a (Figs. 9 and 10) and pull the said slide 339 continually downwards, a roller 344 on the slide being pulled against the cam 289. I-Iereby the normal position of the release slide 339 is determined. A lever 345 is engaged by a stop 346 fixed to slide 339. Lever 345 is swingably mounted on a headed screw 341 by means of a hub 348, said screw 341 in turn being screwed into a bearing angle 349 and fixed to same by means of a lock nut 358. A spring 352a connected to the lever 345 and to a pin 352 fixed to the inside of the back wall of the casing l8, draws the lever 345 upwardly against an eccentric disc 35! fixed to a zero-setting slide 352!) (Fig. 8) by means of a nut 353 and a screw 354. The zero-setting slide is thus held with the lower end of its slot 355 pressed against a guide screw 356 and isthereby held in its normal position. The guide screw 356 is fixed in the bearing angle 349 by means of a nut 351. The bearing angle 349 is screwed to the back wall 358 of the casing ID by means of screws 359. The zero-setting slide 3521; is guided by means of its slot 355 and screw 356, so as to be non-displaceable in lateral, forward and backward directions but shiftable in a vertical direction. The upper end of the zero-setting slide 3521) is guided by a pin 360 extending into a slot 36! of the zero-setting slide 352b so as to be nonmovable in forward and backwarddirections but shiftable in a vertical direction, and further guided in the upper guide plate 340 for the differential members against movement in a lateral direction. The bolt 36!) is riveted into an angle member 362, which in turn is screwed to the inner face of the front wall 2!4 of the casing by means of screws 353 (Fig. ,3). By means of screws 364 a bridge piece 365 is screwed to the zero-setting slide 352b, the teeth along one edge of the bridge piece 365 engaging a toothed wheel 361, which in turn is fast on the shaft 368. .A second toothed wheel 369 is fast on the shaft 368, which shaft is arranged rotatably between a pointed bearing pin 31!) riveted into the bearing angle member 349 and a pointed bearing screw 31! screwed into an angle-shaped bearing member 312. The toothed wheel 369 meshes with a toothed rack 313. The screw 31! is adjustable and fixable in the bearing angle member 312 by means of a nut 314 (Fig. The bearing angle piece 312 is screwed to the left-hand casing H) of side member 315 (Fig. 1) by means of screws 316 (Fig. 3). Riveted to the zero-setting slide 352%) by means of the rivet 311 is an angle piece 318 provided with locking or ratchet teeth 319, a ratchet pawl 380 being capable of acting on said ratchet teeth. The ratchet pawl 388 is swingably mounted on a headed rivet 38! together with another ratchet pawl 382. The headed rivet 38! is riv eted into an angle member 383 screwed to the inside of the side member 315 by means of screws 384 (Fig. 1). The pawl 382 is continually drawn against a bent-off portion 385 of the ratchet pawl 38!) by means of a spring 386. A spring 381 era-- gaging the ratchet pawl 38!! acts continually on the latter and on pawl 382 against the action of spring 386 in an anti-clockwise direction around the pivot rivet 38!, maintaining the ratchet pawl 38!) in operative position in relation to the ratchet teeth 319 of the angle member 318. Riveted to the unlocking or release slide 339 is a stop member 388, capable of acting on pawl 382. Said release slide 339 in turn is capable of acting, by means of an inclined face 2230. (Fig. 9) at its upper end onalug 389 of lever 396, which is swingably mounted on the shaft 224. By a spring 39! connected to the lever 396 and to a lever 392, the lever 399 is continually pressed against a lug 394 of the lever 392 fixed on the shaft 224 by means of a hub 395 and a screw 396. The lever 396 is mounted axially non-displaceable between the lever 392 and an adjusting ring 391 fixed on the shaft 224 by means of a screw 398. By means of a pin 399 the lever 39!) is capable of acting on a lever 46!] mounted on the shaft 48!, which in turn is swingably supported between the back wall of the casing I8 and the front wall 214 of the casing it. Moreover the levers 462 and 493 are mounted on the shaft 40! and provided with the pins 484 and 495 which project into an annular groove 466 of a hub 401 of a toothed wheel 468. The toothed wheel 488 is axially displaceable on the shaft 249 and is provided with catches or projections 469 which project into the slots M6 of a flange 4!! (Figs. 2 and 8) mounted on the shaft 246. Accordingly, the toothed wheel 498 is arranged non-rotatably but axially displaceable in relation to the shaft 248. A spring 4!2 (Fig. 11) attached to a pin fixed to the back wall of the casing l9 and to the lever 460, pulls the lever 49!] continually against the pin 399, and in this position of the members the toothed wheel 488 is out of operative engagement with the teeth 4M of the zero-setting slide 35%. A locking lever M5 fast on the shaft 46! overhangs and is capable of cooperating, in the operative position, with one end of a locking pawl 4!6 (Figs. 1 and 8) for the purpose of locking the members which are fixedly mounted on the shaft 46 I. The locking pawl 4 I 6 passes through a slot M1 in the side wall 315 of the casing I6 and is swingable on a pin M8. The opposi e end 4|9 of the locking pawl M6 projects through a slot 428 of a lock releasing and restoring slide 42!. Under the pull of a spring 422 attached to a pin 423 of the arm 4!!) of the locking pawl M6 and to a pin 424 fixed to the side wall 315 of the casing iii, the locking pawl in its position of rest is continually pressed against the lower end of the slot 428 of the slide 42!. Said slide at its upper end is provided with a slot 425 through which extends a headed screw 428 screwed into the side wall 315 of the casing It,

a distance ring holding slide 42! at the required distance from the side Wall 315 of the casing l3. At its lower end the slide 42! is slidably attached to the machine frame by means of an elongated slot 421 and a screw 428. By means of a spring 429 attached to a pin 439 of the slide 42! and, to a pin 438a of the machine frame the slide 42! is continually pulled with the upper ends of its slots 425 and 421 against the screws 426 and 428, whereby the normal position of the slide 42! is determined. A lever 43! is swingable round a headed screw 432 screwed into an angle member 433 (Figs. 1 and 3) which in turn is screwed to the outside of the side wall 315 of the casing H) by means of screws 434. The lever 43! projects with its forward arm 435 through a slot 436 of the slide 42!, while its rearward arm 431 projects through a corresponding slot of the side wall 315 (Fig. 1) of the casing H3. lhe lever 43! is capable, by means of its arm 431 of acting on the locking pawl 415.

In the operation of depressing the total-taking key l1 and swinging the total-taking key lever 18, this lever 18 acts with its arm 19 on the lower end 294 (Figs. 1. 3, '7) of the slide 293, thereby pushing the slide 293 upwards against the action of its spring 3"]. Consequently, the angle lever 396 is swung in a clockwise direction round
